HYBRID TEA ROSE PLANT, SPECIALLY ADAPTED FOR LARGE-SCALE CULTIVATION FOR CUT FLOWER PRODUCTION Filed Nov. 21, 1967 United States Patent 2,933 HYBRID TEA ROSE PLANT, SPECIALLY ADAPTED FOR LARGE-SCALE CULTIVATION FOR CUT FLDWER PRODUCTION Stefano Calvino, Strada Coldirodi 65, San Remo, Italy Filed Nov. 21, 1967, Ser. No. 684,878 Int. Cl. A01h 5/02 U.S. Cl. Plt.--20 1 Claim The present invention relates to a new hybrid tea rose plant, specially adapted for large-scale cultivation for cut flower production in the open air as well as in greenhouses.
The rose of this invention has been produced by the applicant after several years of extensive research by means of the genetic cross-breeding of different varieties appropriately chosen so as to bring together the desired characteristics in the same plant and create a type of flower meeting the wishes of international flower consumers. The new type of plant had to satisfy the following requirements: (a) The flowers had to be of medium to large size, sufficiently large to provide a color patch in floral compositions but not so large as to become too heavy for export. The color of the flowers had to be included in the medium intensity range of red, brilliant under artificial light yet withstanding discoloration by sunlight and inclement weather, with a special shade appreciated on the market. (b) The flower stems had to be sufliciently long, rigid and straight and had to bear the flower gracefully and harmoniously, with a slender, erect, straight peduncle. (c) The flowers had to bloom easily, even after they had been cut; be resistant to packaging and long-distance shipment after having been cut. (d) The plant should grow vigorously and sprout when grafted on any type of recipient usually employed in large-scale cultivation, recover promptly after pruning and have a greater productivity than normal varieties previously cultivated. (e) The leaves, sufliciently abundant and decorative, had to be particularly resistant to fungus attack generally affecting roses in large-scale cultivation.
Thus a new variety of rose for large-scale cultivation had to be developed, having improved characteristics regarding the quality of the flower and its acceptability by the public at large, as well as the properties of the plant, so as to render its cultivation much more profitable in comparison with other varieties of the same class.
The applicant therefore carried out a thorough research and made numerous atempts which finally led to positive and satisfactory results. Starting in fact from a numerous stock of hybrid varieties produced by fecundation of a previously unknown hybrid variety bearing red flowers with polyantha roses known as Ninfa Rossa variety, it was possible to isolate or select the plant which is the subject of this invention, and finally meet the targets of this research. The rose Ninfa Rossa is a sport (lusus naturae) of the variety Nymph obtained by A. Dickson in 195 3rose flowered, with salmon-coral colored flowers, which has changed the colors of its flowers in red. The parentage of the new rose is an unnamed seedling, red flowered Ninfa Rossa.
The variety which is the subject of this invention is in fact excellently adapted for the large-scale production of flowers to be cut, and represents a considerable improvement on other varieties of the same class.
The variety in accordance with this invention can easily be reproduced in any number of specimens, all of them having the properties of the original plant, by means of one of the development methods for plants commonly used in flower cultivation, specifically by taking from the original plant or a plant deriving from it a bud and grafting the later by known techniques on a'different species of Plant Pat. 2,933 Patented Oct. 21, 1969 rose (the graft recipient) adapted to the soil in which the variety is to be cultivated. It will thus be possible to obtain fully developed plants suitable for producing cut flowers on an industrial or commercial scale, with all the distinctive properties of the original plant.
These properties are listed, by way of example and without any limitations, in the following description based on a set of plants cultivated according to industrial criteria in the open air and in full soil on a sunny hillside at San Remo in the month of September.
Reference should always be made to these climatic and seasonal conditions with regard to the purchase of the plant in the light of the present description. Any differences which, as a result of different conditions of climate, soil or method of cultivation, may be encountered between certain features of the plant and the corresponding ones of the description must be considered normal and do not modify the essence of the present invention, as least so long as it is possible to identify the plant by means of the collection of features given in the description by repeating the cultivation under the same conditions as those of the plants described.
In the description the colors have been named according to the tables of the Horticultural Color Chart by Robert P. Wilson (indicated in the text by the initials HCC) except in those cases in which the colors were absent from the tables or where its indication is sufficiently clear according to common parlance.
